"Something like this is such big energy and big crowd that I can sort of get lost in it and not have to focus on a single person," Ellie revealed to Capital presenter Marvin Humes, about her pre-show nerves for the Summertime Ball at Wembley Stadium today.

Ellie also spoke about her team-up with Calvin Harris on 'I Need Your Love', and says it's a song they've wanted to put out for some time.

"He emailed me a couple of years ago and said do you fancy doing a track," she recalled. "Then we wrote it at his flat in London and recorded it in LA and then again in London and finally it became a track."
